Step 1: Load the mold
Empty or hollow molds are filled with the desired resin material and loaded onto a large device called a spider.
Step 2: Heat the mold
The molds are then rotated slowly in a large oven, allowing the material to be dispersed and softened until it is forced out onto the mold surface to form the desired product.
Step 3: Cool the mold
After the material has been heated, it continues to spin on the spider through a cooling process, which helps to harden and set the plastic material.
Step 4: Unload the mold
Once the part has been properly cooled, operators at Elkhart Plastics facilities unload the mold. Depending on the product, the part will then move on to secondary assembly operations or the quality lab.
This process was first used in the 1950s and has since been perfected and enhanced over the years to allow for larger molds and many different types of materials for various specific applications.
